I use it in a bunch of ways. It really connects my life from all corners.
I have a crazy diet so I've had to research recipes and develop my own cookbook based on what foods I can tolerate so that's all beautifully organized and tagged in evernote and I can cook in kitchen with my tablet or phone and not have to print recipes. I often take pics of a recipe I cooked and add it to my recipe in evernote so I can cook by sight next time and sometimes I even lay out the main ingreds on the counter, snap a pic of those, so I can just fly thru the kitchen to grab my ingreds and make the recipe without all the reading.
I save work and financial documents in evernote, helps come tax time. Also information I need at the doctors office like my medical history. I have separate notebooks like cookbook, healthcare, work, hobbies, church, admin,etc.
I also include lots of hobbies. Everything from shaving resources and hairstyles/wigs I like goes into the "hairstyles" sub-notebook of hobbies. Craft projects, music, writing projects, short stories and poetry, etc.
I have a notebook called Admin. I guess you could consider it Life Administration. Anything I need to access daily. Such as my to-do list, a list of contacts for medical stuff, work schedule, etc. Great to just have one spot for those essential notes frequently referenced.
So yup, that's how I use Evernote!
